I compiled the latest source (master branch) from <a href="https://code.videolan.org/videolan/vlc-android.git" class="">https://code.videolan.org/videolan/vlc-android.git</a> back in December 2016 and everything works fine. I recently pull the latest source (hoping to get some bug fixes) from the same git repository (master branch) and it compiled fine but when running using the updated libvlc, I get choppy video playback. The condition is worst when a 4K video, which tells me that it’s related to GPU acceleration is not being used. Simply swapping out to use the older libvlc works fine again.</div><div class=""><br class=""></div><div class="">I don’t pass any option into the LibVLC instance and I believed the default should already be “<span style="background-color: rgb(225, 235, 242);" class=""><font color="#333333" face="Lucida Grande, Trebuchet MS, Verdana, Helvetica, Arial, sans-serif" size="2" class="">--avcodec-hw=any”. </font></span>I’m not seeing anything suspicious in the log cat. Any idea?</div><div class=""><br class=""></div><div class="">Here is the log:</div><div class=""><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8aa1418/3916] android_audiotrack audio output: GetMethodID(AudioTrack.writeV23) failed</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8aa1418/3916] android_audiotrack audio output: GetMethodID(AudioTrack.writeShortV23) failed</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8aa1418/3916] android_audiotrack audio output: GetStaticFieldID(AudioFormat.ENCODING_DTS) failed</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8aa1418/3916] android_audiotrack audio output: GetStaticFieldID(AudioFormat.ENCODING_DTS_HD) failed</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8aa1418/3916] android_audiotrack audio output: GetStaticFieldID(AudioFormat.ENCODING_DOLBY_TRUEHD) failed</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b87d4208/3cc3] filesystem stream: cannot open file /vendor/etc/fallback_fonts.xml (No such file or directory)</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b87d4208/3cc3] core stream: File reading failed</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b87d4208/3cc3] core stream: VLC could not open the file "/vendor/etc/fallback_fonts.xml" (No such file or directory).</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8203e38/3cc3] core spu text: no suitable access module for `<a href="file:///vendor/etc/fallback_fonts.xml'" class="">file:///vendor/etc/fallback_fonts.xml'</a></div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b83a6198/3cce] android_window window: request 1 not implemented</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b83a6198/3cce] android_window window: request 1 not implemented</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b83a6198/3cce] android_window window: request 0 not implemented</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b83a6198/3cce] android_window window: request 0 not implemented</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b83a6198/3cce] android_window window: request 1 not implemented</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8b0cfc8/3cc3] filesystem stream: cannot open file /vendor/etc/fallback_fonts.xml (No such file or directory)</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8b0cfc8/3cc3] core stream: File reading failed</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8b0cfc8/3cc3] core stream: VLC could not open the file "/vendor/etc/fallback_fonts.xml" (No such file or directory).</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8203e38/3cc3] core spu text: no suitable access module for `<a href="file:///vendor/etc/fallback_fonts.xml'" class="">file:///vendor/etc/fallback_fonts.xml'</a></div><div style="margin: 0px; line-height: normal;" class="">E/ACodec: [OMX.MTK.VIDEO.DECODER.HEVC] storeMetaDataInBuffers failed w/ err -1010</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b81f5370/3ce0] mediacodec decoder: output: 259 unknown, 3840x2160 stride 3840 2160, crop 0 0 0 0</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b87648f8/3cc3] core decoder: buffer deadlock prevented</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b83a6198/3cce] android_window window: request 3 not implemented</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b8b09138/3cc3] core input: ES_OUT_SET_(GROUP_)PCR is called too late (pts_delay increased to 1500 ms)</div><div style="margin: 0px; line-height: normal;" class="">E/NdkMediaCodec: sf error code: -38</div><div style="margin: 0px; line-height: normal;" class="">E/VLC: [b81f5370/3cc3] core decoder: buffer deadlock prevented</div><div style="margin: 0px; line-height: normal;" class="">E/NdkMediaCodec: sf error code: -38</div></div></body></html>
